Influence of the Powder Pack Boriding Mixture on the FeB and Fe₂B Layers

Microstructural Characterization on AISI 4140 Steel Boriding by New and Reused Dehydrated Boron Paste

“…Boriding is a process of surface hardening; it is utilized on ferrous and non-ferrous metallic materials for possible industrial applications [1]. The different studies of microstructural and surface characterization show the benefits of the Fe2B phase and/or the FeB/Fe2B phases obtained by the boriding processes [2,3]. Thus the common point of the researchers is to obtain a Fe2B monolayer, the less brittle for industrial applications and for manufacturing engineering [4].…”
